[0002] The linear automatic close-fitting packaging machine (heat packaging) is a skin packaging device that softens the PE film by heat and quickly exhausts air to closely adhere to the bubble film. The PE roll film and the bubble film are the special film materials for this type of device. Currently, the linear automatic close-fitting packaging machines produced in the market are mainly divided into two types: bubble film sheet type and bubble film roll film type.

[0003] In the packaging of the PCB industry, some PCBs require a packaging mode of first close-fitting packaging (heat packaging) and then secondary vacuum packaging (cold packaging), some PCBs only require a single vacuum packaging (cold packaging) mode, and some PCBs only require a single close-fitting packaging (heat packaging). Then, on the entire packaging production line (including the case of post-stage boxing), it is required that the linear automatic close-fitting packaging machine can meet the function of the conveyor line (machine) in the single vacuum packaging (cold packaging) mode, so as to solve the problem that in the single vacuum packaging mode, the vacuum packaging personnel do not need to take the board from a long distance, and the problems that the equipment does not need to be misaligned to increase the conveyor and occupy a large space.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below.

[0020] As Figures 1 to 5 shown, an automatic switching mechanism for cutting and conveying of a close packaging machine. A conveyor line 1 is provided on the close packaging machine. The conveyor line 1 is a belt conveyor line or a mesh belt conveyor line. A conveying mechanism 2 and a cutting mechanism 3 are provided at the tail of the close packaging machine. The conveying mechanism 2 is located below the cutting mechanism 3. The conveyor line 1 passes between the conveying mechanism 2 and the cutting mechanism 3. The conveying mechanism 2 and the cutting mechanism 3 can be automatically switched and then connected to the conveyor line 1, so that the close packaging machine has both the single-machine packaging function and the conveying function of the conveyor during the production process.

[0021] Among them, the conveying mechanism 2 includes two lifting plates 4, and a plurality of rollers 5 are connected between the upper parts of the lifting plates 4; the conveyor line 1 passes through the surface of the rollers 5; a first lifting cylinder 6 is arranged between the lifting plates 4, the bottom of the first lifting cylinder 6 is fixed, and the piston end of the first lifting cylinder 6 is connected with a pushing plate 7. Both ends of the pushing plate 7 are respectively connected with the lifting plate 5; the bottom of the first lifting cylinder 6 is connected to the frame of the close packaging machine through a first cylinder bracket. Among them, the first cylinder bracket includes a base plate 8 and a profile bracket 9 connected above the base plate 8; the bottom of the first lifting cylinder 6 is installed on the back of the base plate 8. Installation holes are processed at both ends of the profile bracket 9, and bolts are used to connect to the frame of the close packaging machine at the installation holes; guide posts 10 are arranged on both sides of the base plate 8; guide shaft plates 11 are connected to the inner sides of the lifting plates 4; the guide posts 10 pass through the base plate 8, the upper ends of the guide posts 10 are fixedly connected to the guide shaft plates 11, and the lower ends of the guide posts 10 are fixedly connected to the pushing plate 7. Using the guidance of the guide posts 10, when the first lifting cylinder 6 works, it drives the rollers 5 between the lifting plates 4 to lift. In order to reduce the resistance during the up and down movement of the guide posts 10, linear bearing seats 12 are arranged on the outer sides of the guide posts 10. The bottoms of the linear bearing seats 12 are fixedly installed on the back of the base plate 8, and linear bearings are arranged inside the linear bearing seats 12 and are connected in cooperation with the guide posts 10.

[0022] The cutting mechanism 3 includes a cutting outer frame, and a cutting plate 13 is installed on the surface of the cutting outer frame; two lifting cylinders 14 are arranged on both sides of the cutting outer frame, and the lifting cylinders 14 are fixedly installed on the side surface of the lifting plate 4; the left and right sides of the cutting outer frame are connected with a first support plate 15, and the piston end of the lifting cylinder 14 is connected with the first support plate 15. The lifting of the cutting plate 13 is controlled by the lifting cylinder 14, and pressing rollers 16 are installed on the front and rear sides of the cutting outer frame. When switching to the cutting mode, the conveying line below the cutting plate 13 is pressed down by the pressing rollers 16 and hidden in the frame of the close-packing machine.

[0023] A pin cylinder 17 is installed inside the lifting plate 4 through a cylinder seat, and a pin is connected to the piston end of the pin cylinder 17; a first pin hole 18 is formed in the lifting plate 4 corresponding to the pin; the left and right sides of the cutting outer frame are connected with a second support plate 19, a locking plate 20 is connected to the bottom of the second support plate 19, and a second pin hole 21 is formed in the locking plate 20. After the cutting plate 13 descends, the pin cylinder controls the pin to sequentially pass through the first pin hole 18 and the second pin hole 21 to fix the cutting mechanism.

[0024] A jacking cylinder 22 is installed at the bottom of the second support plate 19 at the same time, and the piston end of the jacking cylinder 22 passes through the second support plate 19 and is connected with an extended support bar 23. After the piston end of the jacking cylinder 22 jacks up the extended support bar 23, a widened cutting surface is formed on the cutting plate 13.

[0025] Among them, when only vacuum packaging (cold packaging) is required for the entire linear packaging production line, it is switched from the cutting mode to the conveying mode. The piston end of the lifting cylinder 6 retracts, and the rollers 5 between the lifting plates 4 drive the conveying line 1 to rise to a horizontal state. Then the pin cylinder 17 drives the pin to disengage from the pin hole, and the lifting cylinder 14 drives the cutting plate 13 to rise. After the cutting plate 13 rises to a certain height, a conveying channel is formed between the cutting plate 13 and the conveying line. At this time, the close-packing machine has the function of a conveying line, and the product can continue to be conveyed backward; when the entire linear packaging production line requires close packaging (hot packaging), the packaging machine is switched from the conveying mode to the cutting mode. The lifting cylinder 14 drives the cutting plate 13 to descend. After the lifting cylinder 14 descends in place, the pin cylinder 17 drives the pin to insert into the pin hole to lock the cutting plate 13. Then the lifting cylinder 6 extends, the conveying mechanism descends, and the conveying line 1 below the cutting plate 13 is hidden in the frame of the packaging machine. At this time, the close-packing machine has the cutting function.

[0026] The present invention is not limited to the described embodiments. Those skilled in the art can still make some modifications or changes without departing from the spirit of the present invention, that is, within the scope of disclosure. Therefore, the scope of the protection of the rights of the present invention shall be subject to the scope defined by the claims.
